Specification of Letters Patent.

Application filed December 23, 1909. Serial No. 534,724.

.To all whom it may concern:

Be it known that I, SIGMUND MAYER, a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Urns, of which the following is a full, clear, and exactdescription.

The invention relates to urns for coffee, chocolate, etc.

In practice it is frequently desired to adapt an urn either for makingcoffee or chocolate or other beverages. lVhen the urn is to be used formaking coffee, it is customary to suspend the ground coffee in a bag orreceptacle in a reservoir containing water, this receptacle beingremovable for convenience in cleaning and no means for stirring oragitating the coffee is necessary. When, however, the urn is to be usedfor another l quid, such as chocolate, in which the materlal is mixedwith hot water, it is necessary that a device should be provided forstirring the contents of the urn to render the liquid drawn from the urnof uniform character. When the urn is used for chocolate, it is alsodesirable to have associated therewith a reservoir for hot milk to mixwith the chocolate drawn from the urn, to avoid the necessity ofproviding a separate heater for the milk or liquid to be added to thechocolate drawn from the urn.

It has heretofore been proposed to mount a stirring device in the coverof the urn and to provide a handle on top of the urn for operating thestirring-device. In this construction, a receptacle for milk could notbe employed on top of the urn, because the handle for operating thestirring device would be rendered inaccessible and the handle at the topof the urn would be, in most instances, inconvenient of access.

The present invention designs to provide an improved urn which isadapted for making coffee or for making chocolate or a beverage in whichthe material is mixed with a liquid and requires stirring or agitationand in which the means for operating the stirring device is disposed, sothat the top of the urn may be utilized for heating a liquid to beadded, such as milk, while the stirring-device remains operative in theurn.

Further, the invention designs to provide an improved combined chocolateand coffee urn in which the device for operating the stirring-device isconveniently disposed at the side of the urn and the stirring-device isremovably held in the urn, so that it may be withdrawn and acoffee-receptacle substituted therefor.

The invention still further designs to provide an urn of improvedconstruction.

The invention consists in the several novel features hereinafter setforth and more particularly defined by claim at the conclusion hereof.

In the drawings: Figure 1 is a central vertical section of an urnembodying the invention, being shown as adapted for making chocolate ora beverage made of material admixed with a liquid. Fig. 2 is aperspective of the stirring-device and the means for removablysupporting it in the urn. Fig. 3 is a plan, the top-receptacle of theurn being removed, parts being shown in section.

Fig. 4c is a central section of the urn when it is adapted for makingcoflee or a beverage in which the stirring-device is not necessary.

The improved urn comprises a base 10 which is sustained by legs 11 andin which a suitable heater 12 is disposed. A jacket 13 and 14 mountedupon the base form a reservoir for containing water, which will beheated by the burner 12 and will circulate around and heat a receptacle15 which is disposed within the jacket and adapted to contain coffee orchocolate as may be desired. Receptacle 15 is mounted upon a frame 16resting on the bottom 14 and is provided with a suitable bottom-outlet17 to which is connected a pipe 18 leading to a suitable cook 19 throughwhich the contents of the receptacle 15 may be withdrawn, as wellunderstood in the art. The reservoir is provided with a cock 20, wherebywater may be withdrawn and a suitable inlet 21 is provided to permitwater to be poured into the reservoir, as well understood in the art. Aring 22 is secured to the top of jacket 13 and is provided at its lowerend with a downwardly extending flange 23 which fits snugly into thereceptacle 15 to close the space between the top of the hot waterreservoir and said receptacle.

As shown in Fig. 1, the urn is adapted for making chocolate and isequipped with a stirring-device vwhereby the mixed material and liquidused in making chocolate may be stirred from time to time, or before itis withdrawn from cook 19. This stirring-device comprises suitableblades 24 and 25 secured to the lower end of a central verticallyextending shaft 26. To the upper end of this shaft is secured a pinion27 which meshes with a gear-wheel 28 on a horizontally extending shaft29, whereby the vertical shaft 26 may be rotated to 0perate thestirring-blades in the lower portion of receptacle 15. This mechanism issustained in the urn by supporting-means comprising a ring 30, havinginwardly extending arms 31, a journal 32 for the upper end of shaft 36and vertically extending arms 33 in which the horizontal shaft 29 is journaled. The supporting-ring 30 is adapted to rest on an inwardlyextending annular shoulder 22" of the top ring 22, and is seated uponsaid shoulder by a keeper 34, ring 30 being provided with a notch 35,which permits the ring to be slipped under the keeper, so the latterwill hold the ring firmly seated on the top ring 22. Stops 30 limitrotation of ring 30 to position shaft 29 to receive an operating handle.The outer end of shaft 29 terminates inwardly of the top ring 22, sothat the stirring-device and its support may be conveniently removedfrom the receptacle 15 whenever it may be desired to use the urn withouta stirringdevice, for example, when the urn is to be used for makingcoifee as shown in Fig. 4 when a receptacle 36 for holding ground coffeewill be suspended from a removable ring 37, which is also adapted to beheld by keeper 34.

An operating handle for the stirring-de vice is provided and isdetachably connected to shaft 29, which operates the stirring-device, sothat the latter may be removed while the operating handle remainsconnected' to the reservoir, and resultantly, the operating device mayproject laterally from the reservoir where it will be convenientlyaccessible for operation every time that a cup of chocolate is to bedrawn from receptacle 15. This crank-handle 40 has a stem which ismounted in a journal 41, which is secured to the reservoir 13 by rivets42 and contains a spring 43 for engaging a shoulder 44 on the stem 45 ofcrank 40 to press the crank normally inward. The inner end of thecrank-stem 45 is squared, as at 46 or suitably formed to fit into acorrespondingly shaped socket 47 in the outer end of shaft 29, thusproviding a detachable or slip connection between the operating deviceand the stirring device, which permits the latter to be removedindependently of the operating handle. A screw-collar 48 at the outerend of sleeve 41 provides a sliding and rotative journal bearing for theouter end of stem 45 and also serves as an abutment for the outer end ofspring 43. Then the handle 40 is drawn outwardly against the force ofspring 43, the squared inner end 46 of the crank stem will be withabovethe water-jacket.

drawn from socket 47 in shaft 29 and will disconnect the crank from saidshaft, so that the supporting-ring 30 and the stirring-device carriedthereby may be rotated in the frame to bring notch 35 under keeper 34when it will be free to be lifted from receptacle 15. To insert thesupporting-ring and stirring-device, it is only necessary to pull handle40 outwardly until the ring 30 has been slipped into position to bringshaft 29 into position to receive the inner end of the crank-stem 45whereupon the spring 43 will force the stem inwardly into operativeconnection with said shaft. When the parts are in this position and thecrank 40 is rotated, shaft 29 will be rotated thereby and the stirrerswill be operated by means of the gearing between said shaft and thestirrers.

When the urn is used for chocolate, it is customary to provide a supplyof hot milk to be added to the mixture drawn from the receptacle 15 andfor this purpose a reservoir 50 having a base ring 51 adapted to rest ona shoulder 22 formed in top ring 22 is supported above the reservoir, sothat sufiicient heat from the hot-water reservoir will pass to the milkreservoir 50 sustained Milk-reservoir 50 is provided with a top 52 and acock 53 whereby the milk may be withdrawn at will. This top 52 isadapted to fit on top of topring 22 when the milk receptacle is removed.

The invention thus provides an improved urn with a removablestirring-device and operating means for the stirring-device at the sideof the urn, so that the stirring-device may be conveniently operated,and so that a milk reservoir may be sustained on top of the urn, when itcontains the stirringdevice. Furthermore, the urn may be quicklyconverted for use in making cofiee or chocolate and is simple inconstruction.

The invention is not to be understood as restricted to the details shownand described, since these may be modified within the scope of theappended claims without departing from the spirit and scope of theinvention. 7
